本程序是用于三维图像的，三维重建，非常有用

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.-Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.

这个例子是从Allegro V3.12的例程包中移植过来的,原文件为examplesex4.c 原作者是Shawn Hargreaves.这个程序示范怎样操作调色板,它把一套同 心的圆画在屏幕上并且通过循环调色板产生奇妙的特效.-this example from the routines Allegro V3.12 package transplant, the original document examples ex4.c Shawn Hargreaves is the original author. This procedure demonstrated how to operate a palette, with a set of concentric circular painting on the screen through the cycle and have a wonderful palette of effects.
